Flame Arrester NK-FA22T
GNITION OF GAS/AIR VAPOR-CLOUDS EXTERNAL ATMOSPHERIC EXPLOSION
During filling of a storage tank and depending upon weather conditions explosive gas/air vapor clouds can develop in case they ignite due to external to protect the tank gets in touch with both flame and explosion shock wave. The provided device has to prevent a flashback and long burning poof.

DESIGN AND FUNCTION
Model NK-FA22T type is mounted on the end of a vent pipe from the tank. Vapors are allowed to escape into the atmosphere and air can be drawn into the tank through the flame element. The flame arrester consists of a spiral wound and crimped bank element.
The flame arrester is installed where it is not necessary to conserve vapor losses but low flash point solvent liquid must be protected against fire and explosion from exterior ignition sources.
INSPECTION AND INSTALLATION
All NEOTECHKOREA flame arresters are bi-directional and the installation on a tank or piping system depends to a great extent on the design of the system. The Model NK-FA22T is recommended for vertical installation on roof of tank or venting to atmosphere.
